"We follow you wherever you go" and "the only way to silence us is your eternal sleep", they imply the omnipresence of whatever the thing is around your life, and it will be gone if you died/you cannot experience it after you died. "The more attention you pay to us, the wiser you'll grow.", this line suggests that the thing may bring you wisdom if you focus on it. Wisdom is probablythe ability to think and act based on insight gained from knowledge,common sense,understanding and experience(just paraphrasing Wikipedia), you can pay attention to all of the above to be wiser and lose them for yourself once you are six feet under, however only your life experience will "follow you wherever you go". You may become irrational at the heat of the moment, foregoing your knowledge and you common sense but you will not forego your experience as your experience shapes your subconscious mind and hence constantly influence the decision you make. For example normal people should not remember clearly what happened when they were infants but if they were neglected by their parents when they were crying for help as infants, they may grow up to be the kind of people who would not ask for help because their experience as a baby tell them that no one will help them even if they cry, they do not remember the events but deep inside their mind the feeling that no one will help them lingers, and hence the "follow you wherever you go" even if you loose the memory. "Just try to not get lost, and some to yourself, keep." can also be interpreted in a way that supports my theory that "we" is the life experience of a human being. "try not to get lost" has multiple meanings, on one hand you should not loose memory of what you experienced because it defines who you are and at the same time it also means you should not let your (bad/unpleasant) experience jade you and make you become overly negative etc like the baby example. "and some to yourself, keep", there are some experiences that you may want to keep to yourself because its private or special that other people cannot totally understand and you must remember the feeling. Your experience will be silenced once you died, although you can share your stories of your experience while you are still alive but for instance hearing the horrifying tales of a concentration camp is totally different from living the tales of the concentration camp, other people cannot experience the same thing as you did through a third-person perspective so your experience which you experienced first hand will be unique to you and it will disappear once you died. In conclusion "we" is the life experience of a human being.
